摘要
提出浆料混合法配制热塑性树脂改性聚醚酮(PEK-C)增韧的双马树脂,研究浆料混合法配制的双马树脂及其T700碳纤维预浸料的基本性能,并与传统热熔法进行比较。结果发现,与传统热熔法相比,浆料混合法显著提高树脂和预浸料的粘性和室温储存稳定性,预浸料由传统的无粘性变成粘性和可操作性良好,室温粘性和力学性能储存期由原来的20天提高到至少三个月以上,并且制备预浸料的涂布头温度和热压辊温度可降低30-40℃左右,明显改进了预浸料的制备工艺。复合材料的力学性能和耐热性测试结果表明,改变树脂配制方法对复合材料的力学性能和耐热性没有影响。
Slurry mixing process was used to prepare modified polyetherketone (PEK-C) toughened BMI resin, and the properties of prepared BMI resin and prepreg were investigated and compared to those from traditional hot melt mixing process. Results indicated that the BMI resin and prepreg prepared from slurry mixing process had good stickiness and storage stability, and the room storage life of prepared prepreg was at least 3 months by determining both stickiness and mechanical properties, while the stiff prepreg without stickiness prepared with the resin from traditional hot melt mixing process had only 20 day room storage life by determining mechanical properties. The prepreg processing temperature was lowed 30 -40℃ by using slurry mixing resin. The change of resin mixing process had no influence on mechanical properties and heat resistance of composite.
